First trimester

1 Week Pregnant

The very beginning

How your baby is developing

  • Pregnancy is dated from your last period, so conception has not happened yet.
  • This is the starting line rather than a milestone to feel.

What may be happening in your body

  • Your body is simply beginning its cycle — there is nothing to notice yet.

How you may be feeling

  • Hope, nerves, or disbelief can all show up at the very start.
  • There is no right way to feel this early.

Worth remembering

Everyone's starting point is different, and a quiet week one is completely normal.

Something you can do this week

Being gentle with yourself is enough today.

What comes next

Over the next couple of weeks your body prepares, still on a scale far too small to feel.
